经眶颧弓入路切除巨大颅底脑膜瘤

Orbitozygomatic approach to giant skull base meningioma

目的 探讨眶颧弓入路开颅术在切除颅底脑膜瘤中应用价值。 方法 经眶颧弓入路切除巨大颅底脑膜瘤20例，观察手术效果。 结果 肿瘤全切除13例，次全切除4例，部分切除3例。无严重并发症，死亡1例。随访4个月～2年，17例恢复正常工作，2例在康复中，其中1例需人照顾。 结论 眶颧弓入路适用于切除颅眶沟通脑膜瘤、蝶骨嵴扁平型脑膜瘤、巨大蝶骨嵴内侧型脑膜瘤、海绵窦脑膜瘤及部分岩斜脑膜瘤。

Objective To evaluate the value of orbitaozygomatic approach used for removal of the giant meningiomas originating in the skull base． Method 20 cases of skull base meningioma were removed via orbitozygomatic approach, and the results observed． Result Tumor was totally removed in 13 cases, sub totally removed in 4 and partial removed in 3． There were no severe complications． One patient died of acute nephrenal failure 16 days after operation． Conclusion It suggested that orbitozygomatic approach could be applied for the meningiomas originating in the orbit, medial sphenoidal wing, and cavernous sinus or petroclivus region and sphenoid wing meningiomas enplaque．
